IselcelosesZiya zisiba zisetyenziswa kwizinto ezisekwe kwizithembiso, ngakumbi kwizifa ezomileyo, ngenxa yokugcinwa kwabo amanzi kunye neziphumo zokonwaba. Ke ngoko, iipropathi kunye nendlela yokwenziwa kwendlela yeI-Selersese Ether Izinto eziguqulweyo zesamente eziguqulweyo kunye nonxibelelwano phakathiI-Selersese Ether Kwaye i-cerry slicry ngokuthe ngcembe iba yinto egxile kuyo kwicandelo lezinto zokwakha kunye nobunjineli kule minyaka idlulileyo. Iziphumo ezininzi zophando zifezekisiwe. Ukudibanisa inkqubela phambili yophando ekhaya kunye phesheya, kusekho ezi ngxaki zilandelayo kuphando kunye nokusetyenziswa kweI-Selersese Ether Izinto eziguqulweyo zesamente:
1. Iindidi ezininzi zeiselceloses.Nokubaiselceloses Isetyenziswe kwizixhobo ezisekwe kwimo yesamente yahlulwahlulahlulahlula iintlobo ezininzi njenge-HEC, i-HMC kunye ne-HPMC ngenxa yenqanaba labo lokufaka endaweni. Uhlobo olufanayo lweiselcelosesYiba nolwahluko omkhulu kwimo yemolekyuli, ubunzima bemolekyuli, isidanga sokufaka okanye umxholo ophantsi. Okwangoku, uphando oluphambili ekhaya nase-phesheya lugxile kwelinye okanye eliliqelaiselceloses.Ukhetho lweisellulose ether inqunyelwe kumacandelo abo esicelo. Ulwakhiwo lwemolekyuliiselceloses aziboniswanga, kwaye ukungeneka kwabo akukho mmeli. Isiphelo sisiphumo esingenakufikeleleka "sokufakwa endawenilenye", kwaye kukho ukungangqinelani kunye neengxabano phakathi kweziphumo zovavanyo. Ke ngoko, kuyimfuneko ukuba ufunde ngokucwangcisiweyo kunye neepropathi zolwakhiwo kunye neendlela zeentlobo ezahlukeneyo zeI-Selersese Ether Izinto eziguqulweyo zokulungisa.
2.Ukubhala uncwadi ufunde impembelelo yeiselceloses kwiimpawu ezahlukeneyo zezinto ezinesakhiwo, kwaye ziqhube nohlalutyo oluthile lwendlela yayo, kodwa zasilela ukumisela ubudlelwane phakathi kwesakhiwo semolekyuli yeiselceloses kunye neepropathi zesamente eguqulweyo. Ukuya kwahluka, kwaye kukho umahluko ocacileyo kwiindlela zabo. PhakathiI-Selersese EtherIzixhobo ezisekwe kwimo yesamente, zimbalwa izifundo kwizixhobo kunye nezakhiwo ezahlukeneyo zemolekyuli, ezingenakuchaza indlela yokwenziwa kweendlela ezahlukeneyo zepropathi ezahlukeneyo zeI-Selersese EtherIzixhobo ezisekwe kwiSamente. . Nangona ezinye iincwadi zafumanisa ukubaiselceloses Ngezakhiwo ezahlukeneyo zeemolekyuli zineziphumo ezahlukeneyo kwi-qument yesamente, izizathu eziphantsi zenzekile.
3.Undlela yempembelelo yeI-Selersese Ether Kwi-ceracy kinetics kinetics ihlala ifundwa. Okwangoku, malunga nendlela yokuyibamba i-hydimed yeI-Selersese Ether, nangona i-adsornge ithathwa njengeyona nto ibalulekileyo yokulibaziseka i-hydimed yeI-Selersese Ether, kufumaniseke ukuba ukomelela komthamo we-adsorction phakathi kweemveliso ze-hydration kwayeI-Selersese Ether, ukukhonkotha okukholiba ngakumbi kwesamente. Indlela ye-adsorction phakathiiselceloses kunye neemveliso ze-hydration, kunye nezizathu zezakhono ezahlukeneyo ze-adsorction ezahlukeneyoiselceloses kunye neemveliso ze-hydration, azikhange zifundwe.
4.Uncwadi uncwadi lubonisa ukubaiselceloses inokuchaphazela kakhulu ukwakhiwa kwezinto ezisekwe kwizixhobo.Iselceloses Kukwakholelwa ukuba isebenze nzima kwaye ibe nefuthe lokutyibilika nge-cemes entsha, ngaloo ndlela kukhulisa ukuthambeka kwe-qumed eqingqiweyo. Nangona kunjalo, impembelelo yeiselceloses Kwindlela yesiqhelo kunye nendlela yokwenziwa kwenkqubo yesamente ye-slrery pore
I-5. Iipropathi ze-ROOOLOPRTERS yinkalo ebalulekileyo yokusetyenziswa kweiselceloses kwizixhobo ezisekwe kwisamente. Ngelishwa, zimbalwa izifundo kwiipropathi ze-ROOOOOOOIRTEI-Selersese Ether Isamente eguqulweyo ekhaya nakwa kwelinye ilizwe.
